Phoenix is a privacy VPN. There is no account, no sign-up, no email and no password - the app issues an anonymous key to the device on first launch. How to test: open the app, tap Start, then tap the large connect button on the main screen. iOS will show the standard prompt asking to add a VPN configuration - please tap Allow, as this is required for any VPN app to function. The tunnel then carries live traffic; open any IP lookup site before and after connecting and the reported address will change. Please report connection reliability, reconnect behaviour after switching between Wi-Fi and cellular, and anything unclear in the subscription screen.
